微塑料(MP)是一种环境污染物,对海洋系统构成威胁。在这里,我们报告的数据,从城市瓜纳巴拉湾的表面沃茨收集的MP的丰度和特点。通过两次浮游生物网的水平拖网采集样品(2016年夏季)。通过筛分从样品中获得MP,并且用显微镜手动分选颗粒。通过重量分析和数字图像处理(用于定量和形态分类)完成MP的表征,并通过红外光谱和元素分析鉴定化学组成。总的微塑料颗粒从1.40到21.3颗粒/立方米不等,这使瓜纳巴拉湾成为全球微塑料污染最严重的沿海系统之一。≤1 mm的聚乙烯和聚丙烯聚合物是最丰富的颗粒。因此,在瓜纳巴拉湾的MP的发生是相关的,以了解生态危害的暴露对海洋生物群和值得进一步调查。
Microplastics (MPs) are contaminants of environmental concern that represent a threat to marine systems. Here we report data on the abundance and characteristics of MPs collected from surface waters of the urban Guanabara Bay. Samples were collected, by horizontal trawling of a plankton net on two occasions (summer of 2016). The MPs were obtained from samples by sieving and particles were manually sorted with microscope. Characterization of MPs was accomplished by gravimetry and digital image processing (for quantification and morphology categorization), and chemical composition identified by infrared spectroscopy and elemental analyses. Total MPs ranged from 1.40 to 21.3 particles/m3, which places Guanabara Bay amongst the most contaminated coastal systems worldwide by microplastics. Polyethylene and polypropylene polymers ≤1 mm were the most abundant particles. Therefore, the occurrence of MPs in Guanabara Bay is relevant to understand ecological hazards of exposition to marine biota and merits further investigation.
